The De Niro and Biden packages bring the number of suspicious packages sent to prominent critics of President Donald Trump this week to at least nine.

Authorities responded to 375 Greenwich Street in Tribeca in the vicinity of Greenwich and Franklin streets. The address matches that of Tribeca Enterprises, Robert DeNiro’s film and television production company and organizer of the Tribeca Film Festival. The site also contains DeNiro’s Tribeca Grill restaurant.

Police have sent the package to a secure facility in the Bronx, New York Police Department Commissioner James O’Neill said on Twitter.

“The most highly trained experts in the world are investigating today’s suspicious package in #TriBeCa,” O’Neill’s tweet reads.

X-ray images show that the package addressed to De Niro contains a device similar to the pipe bombs found in other packages this week that were addressed to prominent Democrats, the two sources said.

De Niro is a vocal critic of President Donald Trump.

Police were called at 4:45 a.m. Thursday about the package, which was on the building’s seventh floor.

And, just as the other packages, the one sent to De Niro had six American-flag stamps arrayed in two rows. No postmark is visible on the front of the De Niro package, similar to some of the others, the sources said.

Meanwhile, authorities have located a suspicious package addressed to former Vice President Joe Biden in Delaware.

A law enforcement source said the package addressed to Biden was intercepted at a Delaware mail facility and was similar to the others. The official wasn’t authorized to discuss an ongoing investigation publicly and spoke on condition of anonymity.

Police have cautioned people to avoid the area and expect heavy police presence and traffic.

Authorities found bombs this week intended for at least seven officials, including Hillary Clinton, Barack Obama and Democratic Rep. Maxine Waters. The five packages discovered Wednesday all had a similar address: That of Democratic Congresswoman Debbie Wasserman Schultz, but with her name misspelled. There is no information to suggest she sent the packages.
